The wife and I spent two nights at the Williamsburg lodge over Presidents' Day weekend with their room and spa package. For whatever reason the package was cheaper than just the normal room rate so we got a pretty good bargain. The room was well appointed although the beds are not the most comfortable. Also, the wife really liked the spa products that they have in the bathroom.
We spent about day waking around Colonial Williamsburg. If you stay at the hotel, admission to Colonial Williamsburg is about $24 per person I believe, and would be valid for the entire stay. We also spent some time at the Lodge Lounge (for some late night snacks/dinner) and at the spa facilities and they were both excellent.
